MABY4500 Sustainable Concrete Structures Emneplan

This course deals with sustainability and service life of concrete structures. Concrete bridges, quays, dams and foundations etc. are important infrastructures for the society, and often exposed to severe environmental loadings. Concrete is the most used construction material in the world and the production of cement accounts for about 8% of the global greenhouse gas emissions. Possible measures to reduce the carbon footprint are by use of concrete types with supplementary cementitious materials. In order to reduce the total greenhouse gas emissions from concrete structures, climate adapted service life design together with service life extension measures (i.e. structural health monitoring, repair and upgrading) are decisive.

The course provides studies in topics such as:

• Low-carbon concrete and greenhouse gas emissions
• Transport and degradation mechanisms of reinforced concrete
• Service life prediction and service life design of concrete structures
• Inspection and non-destructive testing
• Condition assessments and residual service life of existing concrete structures

Language of instruction: English

After completing the course, the student is expected to have achieved the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge:

The student;

• has advanced knowledge of low-carbon concrete types and their application in concrete structures.
• has advanced knowledge of relevant degradation mechanisms for reinforced concrete.
• has advanced knowledge in modelling of chloride induced corrosion and service life.
• has knowledge of inspection strategies and test methods for conditions assessment of concrete structures.
• has in-depth knowledge of the structural consequences of reinforcement corrosion on the load-bearing capacity of concrete structures.
• has knowledge of various repair and strengthening measures for existing concrete structures.

Skills:

The student is capable of;

• designing concrete structures that fulfil Eurocode 2 requirements for durability and service life.
• performing service life predictions for concrete structures in marine environments.
• performing calculations of greenhouse gas emissions for concrete structures.
• proposing measures to extend the service life of concrete structure.
• performing capacity assessments of a damaged concrete structure or component.

General competence:

The student is capable of;

• understanding and analyzing scientific publications on topics related to sustainability and durability of concrete structures.
• applying theories in practice based on scientifically justified choices of relevant sustainable solutions.
• presenting academic results and evaluations in a scholarly manner

The teaching consists of lectures and exercises. The students will also be given a major project assignment, in groups of 2-3 students. The project assignment shall be presented in the form of a scholarly report.

Three individual exercises must be approved before the student can take the exam.

Students who fail to meet the coursework requirements can be given up to one re-submission opportunity before the exam.

The assessment (exam) is a project assignment (portfolio) consisting of two components:

• Project report prepared in groups of 2-3 students
• Oral exam; project presentation and questions from the sensors

The exam will be assessed as a whole with one final grade.

The exam may be appealed. Upon appeal, the written work will be reassessed, and the student must complete a new oral presentation/exam.

In the case of a group examination, the right to appeal is individual. This means that each group member may only submit an appeal on their own behalf. A student who submits an appeal must complete the oral presentation individually. Failure to attend will result in the grade "did not attend" for the entire course.

In the event of a resit or rescheduled exam, oral examination may be used instead. If oral exams are used for resit and rescheduled exams, the result cannot be appealed.

All aids permitted.

Graded scale: A-F.

Two internal examiners.

External examiners are used regularly.
